Humanity may already be living far beyond what Earth can sustainably support, according to a sweeping new study analyzing more than 200 years of population and environmental data. Researchers found that while population growth once fueled innovation and expansion, the trend shifted decades ago as the planet’s resources became increasingly strained.

The French Riviera may look like an unlikely place for a tsunami disaster, but scientists warn the threat is far more real than most people realize. Historical events and new modeling show that destructive waves have already struck the Mediterranean coast — and could hit again with very little warning. Some tsunami scenarios could reach…

Scientists in Canada have discovered that ancient underground rocks are naturally producing hydrogen gas — and lots of it. Measurements from mine boreholes in Ontario show the gas can flow continuously for years, offering a potential new source of clean energy called “white hydrogen.” Researchers say this hidden resource could help power industries and remote…

Scientists in Australia are using cutting-edge DNA techniques to help save one of the world’s rarest marsupials — the critically endangered Gilbert’s potoroo, with fewer than 150 left in the wild. By analyzing tiny traces of DNA in the animals’ scat, researchers uncovered clues about the elusive fungi the potoroos depend on for survival. The…

Deep beneath Portugal’s São Jorge Island, a massive surge of magma silently pushed upward from more than 20 kilometers underground in 2022, triggering thousands of earthquakes and briefly raising fears of a volcanic eruption. Scientists discovered that the molten rock climbed astonishingly fast — enough to fill 32,000 Olympic swimming pools — before stalling just…

Scientists exploring deep underwater canyons off the coast of Western Australia uncovered a hidden world packed with bizarre and elusive marine life — including signs of the legendary giant squid. By analyzing traces of DNA floating in seawater from depths exceeding 4 kilometers, researchers identified 226 species ranging from deep-diving whales to strange fish rarely…

Humans may have returned to Britain far earlier than scientists once believed — not long after the last ice sheet began retreating. New evidence suggests people were already moving into the British Isles around 15,200 years ago, tracking herds of reindeer and horses across a landscape that was suddenly becoming warmer and greener.
